Heh, that's my daughter - mostly self-taught with just enough misdirection from me to keep her guessing. The essay was from 1995, but was just in a listserv. The webpage was done in the early 2000s.
My dad, John Perry, wrote this essay and followed it up with a book - The Art of Procrastination. I love to see the essay rediscovered & will share this thread with him.
